Journal ArticleDOI
Disintegration of the scrophulariaceae.
Richard G. Olmstead,Claude W. dePamphilis,Andrea D. Wolfe,Nelson D. Young,Wayne J. Elisons,Patrick A. Reeves +5 more
TL;DR: A molecular systematic study of Scrophulariaceae sensu lato using DNA sequences of three plastid genes revealed at least five distinct monophyletic groups, which are newly erected herein to recognize the phylogenetic distinctiveness of tribe Calceolarieae.
Journal ArticleDOI
Mitochondrial DNA suggests at least 11 origins of parasitism in angiosperms and reveals genomic chimerism in parasitic plants
Todd J. Barkman,Joel R. McNeal,Joel R. McNeal,Seok Hong Lim,Gwen Coat,Henrietta Brown Croom,Nelson D. Young,Claude W. dePamphilis +7 more
TL;DR: The results of a phylogenetic analysis of 102 species of seed plants indicate that the parasitic lifestyle has arisen repeatedly in angiosperm evolutionary history and results in increasing parasite genomic chimerism over time.
Book ChapterDOI
Molecular Phylogenetic and Evolutionary Studies of Parasitic Plants
Daniel L. Nickrent,R. Joel Duff,Alison E. Colwell,Andrea D. Wolfe,Nelson D. Young,Kim E. Steiner,Claude W. dePamphilis +6 more
TL;DR: This work uses the term parasite in a strict sense to refer to haustorial parasites, which represent about 1% of all angiosperms and are restricted to the dicot subclasses Magnoliidae, Rosidae, and Asteridae.
Journal ArticleDOI
The evolution of parasitism in Scrophulariaceae/Orobanchaceae: plastid gene sequences refute an evolutionary transition series.
Journal ArticleDOI
Multiple major increases and decreases in mitochondrial substitution rates in the plant family Geraniaceae
Christopher L. Parkinson,Christopher L. Parkinson,Jeffrey P. Mower,Yin Long Qiu,Yin Long Qiu,Andrew J. Shirk,Andrew J. Shirk,Keming Song,Nelson D. Young,Claude W. dePamphilis,Jeffrey D. Palmer +10 more
TL;DR: That the mitochondrial mutation rate has returned to normally low levels in many Geraniaceae raises the possibility that, akin to the ephemerality of mutator strains in bacteria, selection favors a low mutation rate in plant mitochondria.
